辽河盆地齐3-17-5块微幅度构造成因研究及其对区块开发的意义

The Formation of Mini-structure Analysis in the Qi 3-17-5 Region of Liaohe Basin and Its Importance to the Block Development

油田地质综合研究的结构研究是一个重要组成部分的内容,3-17-5块之前的结构图等高线间距比较粗糙很难准确地反映较小的变化。它不是一种微观的结构图。将等高线间隔定为5m才能为进一步精细解释油藏,并对其结构进行分析和研究。利用钻井及动态资料,结合三维地震资料,对齐3-17-5块进行了微幅度构造(以下简称微构造)特征的研究,依据微构造形态将其划分为正向微构造、负向微构造和斜坡微构造,其具体包括小高点、小断鼻、小槽沟、小断沟等,从而分析出微构造形成原因,及其对区块进一步开发的深远意义。

In the geological comprehensive study, structure research was an indispensable part of content. The contour map of the Qi 3-17-5 structure spaced 50 meters before. It was sketchy and difficult to finely reflect small changes in the structure. It was a macro structure maps. In order to further interpret oil reservoir, in this research the contour map of the structure spaced 5 meters. By using drilling and dynamic information, combined with the 3D seismic data, it could be better to interpret the structure. To research features of the mini-structure （hereinafter referred to as the mini- structure） of the Qi 3-17-5 region, according to the structure form, it can be divided into positive micro structure, negative micro structure, slope micro structure, including small highs, small structure, small faults nose and so on. We could analyze the mini-structure formation and its importance to this block development.
